Abstract.
However, the latter has been comparatively well studied and also contrasts with central Africa in some key climatic features, such as proximity to the Atlantic versus Indian Oceans, the occurrence of rainfall in the boreal summer, and the influence of the Rift Valley highlands and the barrier they provide between the two regions.
Illustration of the different key features, present on the WASA/F map of 19 July 2006 0600.

Introduction
Industrial corporations comprise many different disciplines from mechanical engineering to industrial
engineering up to computer science.
The applied range of motion and discretization are the key-players for providing a high usability of our concept.
• Material flow: Just as between the production areas, optimal material flow should be found for the working stations (Figure 13 b)
For example, bottlenecks in the material flow in relation to the workload of the machines can easily be noticed and associated adjustments can be realized (see Fig. 14 c).
Test users were able to work with a prototype version of the application and(a) (b) (c) (d) Fig. 14: Exemplary, combined views for factory layout planing tasks: (a) combined view from production facilities and distances, (b) combined view from production facilities and material flow, (c) combined view from material flow and workload, (d) combined view from workload and distances.

Abstract.
Microstructure of a Material and Fractography Microstructure of a Material.
In order to discuss the microstructure of the tested materials, SPM observation was carried out using a sample prepared by electro-etching in which the treatment carbides in the material rose to the surface, and a matrix around the carbides was preferentially polished off.
Sizes and distribution of convex particles in the GBF area correspond to those of carbide ones in the microstructure of the tested materials.
The transition of the fracture mode depends on microstructure of the materials, surface treated conditions and also the residual stress distribution in surface layer.

The modal parameter identification of large engineering structures have an important sense to applied civil engineering such as health monitoring, structure damage estimate, active control (fuzzy control), etc [1].
So the modal parameter based on ambient vibration has been adopted extensively in engineering applications.

The material properties, coupon geometry and
the loading spectra are given in [8].
The crack growth threshold of the material may be limiting the number of spectrum cycles that are contributing toward crack growth.
An accurate estimate of the relative severity is a key element in the success of the EBA as a predictive methodology.
